Lube oil treatment for gas turbines
Clean Oil. Reliable Turbine Operation. GEA’s lube oil treatment systems keep your turbines protected and performing at their best day after day.
Why lube oil treatment matters
In gas turbine power plants, lube oil plays a vital role in protecting rotating components and ensuring smooth, efficient performance. Over time, however, the oil becomes contaminated with fine metal particles, dust, condensate and decomposition products. These impurities settle in the lube oil sump and accelerate oil aging especially when acids react with contaminants.
Water ingress is another critical issue. If not removed, it promotes oxidation and bacterial growth, leading to premature oil degradation and increased maintenance needs. Left untreated, these issues can compromise turbine reliability and increase downtime.
GEA’s treatment solution
GEA offers a proven solution: centrifugal separation for purification and dewatering. This method is both efficient and economical, ensuring that your lube oil remains clean and your turbine protected.
Our systems are designed for continuous operation and use advanced centrifugal technology to remove contaminants without interrupting turbine performance. Whether your plant runs on low solid oils or faces challenging operating conditions, GEA’s solution ensures reliable purification and minimal downtime.
Optimizing performance
For best results, especially with higher-viscosity oils, pre-heating is recommended. GEA systems support electric, steam or hot water heating to reduce oil viscosity and enhance separation efficiency. Lower viscosity improves clarifying and separating performance, helping maintain oil quality over time.
Your benefits
With GEA’s lube oil treatment systems, you gain:
- Extended oil life and reduced replacement costs
- Lower maintenance and fewer unplanned shutdowns
- Improved turbine reliability and performance
- Compact, field-proven systems ready for seamless integration

Centrifugal Separator
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...
Machine automation & control
Every plant or machine, which is designed for a reliable long-term operation, requires a control unit that enables the communication between the different system parts. It is one of the most important component that guarantees reliability and efficient operation.
